[A Surgical Case of Intrapulmonary Bronchogenic Cyst Treated by Left Lower Lobectomy for Hemopneumothorax and...

A 79-year-old female visited a hospital because of high fever and computed tomography(CT)showed a cystic lesion with fluid accumulation in her left lung. She had hemoptysis and left chest pain 3 days after antibiotic therapy was started. Chest CT demonstrated the cystic lesion rupturing and causing hemopneumothorax. Then she was referred to our department and thoracic drainage was performed. However, a week after the drainage, she had hemoptysis and chest pain again, and the left lower lobectomy was performed. Histopathological findings showed the cystic lesion was intrapulmonary bronchogenic cyst. We describe a rare case of the hemopneumothorax due to the hemorrhage in the bronchogenic cyst.
